The problem is, the ``COPTS=-O3 -m68040'' goes directly into the
generated .../compile/KERNELNAME/Makefile (see for yourself), where
it overrides any environment variables. There's nothing you can do
later, in any included file, to get the environment variable back.

So try this instead:

makeoptions     COPTS+="-O3 -m68040"
